Not sure what you mean by the war being politically beneficial for Putin when the war has always been about Russia’s national security. Doesn’t matter if Putin or some other leader is in power, they just weren’t going to allow Ukraine in NATO. There is no denying that no matter what, it’s in the US best interest to weaken a geopolitical rival but it’s not sustainable to keep this going long term. We do not have the current production rate to mass produce the weapons Ukraine needs in a cost effective way and most importantly Ukraine doesn’t have the manpower to keep this going either.
Can’t say Russia is being militarily degraded either. Have they lost a lot of military personnel and equipment, absolutely but they are able to replace those loses. They’ve had only one mobilization and that was back in the fall of 2022. They’re recruiting 30,000 volunteers monthly now for the army. They are able to replace their equipment loses because they have a large industrial base and people with the necessary skill set to do it. The German Defense Minister Boris Pistorius just said in an interview last week that Russia is now producing more weapons than what’s needed for the war in Ukraine. The head of US European Command also told Congress the Russian army is now 15% larger in comparison to when the war started. If anything, we’ve taught them how to fight a modern conventional war.
